【 摘 要 】

Practical use of building structures with enclosed spaces is determined by their corrosion resistance requirements. These requirements are implemented and applied in closed spaces spans for pedestrian bridges built in Khabarovsk in Gogol and P. Morozov streets. Implementing of such a constructive solution raises a question of climatic factors effect on confined space and as a result the strain-stress state of the box-shaped span. The article deals with the issue of changing the pressure inside a closed loop span of pedestrian bridge when the ambient temperature changes. The amount of distributed pressure on the elements of a box span was defined on the basis of the Mendeleev-Klayperon equation. The results of stress state change of box-shaped span elements with a closed space depending on the ambient temperature changes were achieved by means of numerical simulation.
